GEORGE BOHNER, OF CHICAGO, ILLINOIS.

LAMP.

SPECIFICATION forming part of Letters Patent No. 250,049, dated November 29, 1881,

Application filed April 18, 1881.

To all whom it may concern:

Be it known that I, GEORGE BOIINER, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Lamps, of which the following is a full description, reference being had to the accompanying drawings, in which Figurel is a side elevation; Fig. 2 is a detail.

My invention relates to that class of lamps which have revolving reflectors for the purpose of causing the light to be thrown by the re flcctor to different parts of the room, as may be desired. I have heretofore obtained a patent for such a lamp in which the lamp is stationary, while the reflector can be rotated around the lamp.

My present invention consists, chiefly, in a bar pivoted upon a lamp bracket or support and extending from the pivotal point in opposite directions. One end of the bar carries the lamp, and at the other end is a support for a reflector.

The construction of the parts is such and the longitudinal bar is so sustained on its support that the lamp and reflector can be made to revolve, and thus describe a complete circle, which is an essential characteristic of the im provements, as itenables the light to be thrown to any part of the room.

In the drawings, A represents an ordinary lamp-bracket, t0 the outer end of which is secured a support, a, for a lamp.

1) is an adapter, being a separate piece screwed upon the top of a, and it has a pin or stud, c.

B is a bar, provided with a hole, by means of which it can be placed upon the stud 0, so as to rotate around it. At the outer end of this bar B is any suitable lamp-support (I. As shown, C is a basket supported on d and carrying the lamp D. The opposite end of the bar B is curved upward, and at its upper end is a socket, e, to receive and hold a reflector, E.

In use the bar B can be rotated upon its support, causing the lamp and the reflector to rotate together around the pivotal point, throwing the light to any desired part of the room.

The adapter I) with its cylindrical stud c being detachably screwed upon its support a, is therefore adapted to many of the ordinary brackets now in use, such, for example, as an (No model.)

ordinary gas-burner bracket. To accomplish this the adapter is interiorly recessed and screwthreaded, and by simply removing the usual gas-burner from its bracket the adapter can be screwed thereon, and the longitudinal bar B with its attached parts can thus be sustained above the gas-bracket and be adapted to describe a complete circle, for the purpose of throwing the light to any part of a room.

By means of the bar B a short bracket, A, can he used, and the lamp can be placed at a greater distance from the wall than when applied directly to such short bracket.

The reflector can be turned by taking hold of that end of the bar B which supports the lamp, which often will be a convenience, especially when seats are arranged beneath the lamps, as is frequently the case.

A pin or stud mightbe used as the pivot for the bar B instead of the adapter shown in the drawings, or a pin could project from the under side of the bar B and enter a hole in the bracket A.

The support a might be cast with the bracket A instead of being screwed thereto, as shown.

The inner end of the bar B may be provided with a pin to receive a reflector in place of a socket.

Heretofore a bracket-lamp has been composed of a horizontally-swinging support carrying at its outer end a pivoted bar, to which is attached a reflector and a lamp; butin such the pivot of the bar is not between the reflector and the lamp, asin my structure; and, further, the said bar cannot be revolved on its pivot so as to describe a complete circle, as in my invention, because the swinging movements of the bar are limited by the support to which it is pivoted. By placing the pivot of the bar at the center thereof, and sustaining said bar according to my invention, I am enabled to cause the reflector and lamp to describe a complete circle, whereby it is possible to throw the light to any part of the room whatever, which I deem of considerable advantage in this form of walllamps.

A hanging lamp has also been composed of a curved and bent hanger suspended from the ceiling, and provided at its lower end with a stud, on which is pivoted a bent tube carrying at one end an Argand burner and at the other end an oil-fount, to which is attached areflector,

thefount supplying the burner through the bent tube, and the pivot of the latter being between the fount and the burner. Such structure is not only exceedingly expensive, but it cannot be applied to a wall, and, further, the construction of the hanger and burner is such that the latter cannot describe a complete circle, as in my invention.

What I claim as new, and desire to secure by Letters Patent, is as follows:

1. Thelongitudinal bar B, loosely pivoted intermediate its ends upon a cylindrical stud on a horizontallyprojecting bracket or support, and capable of describing a complete circle around its pivot, one end of said bar being provided with a lamp and the other with a reflector, which is directly attached to said bar, the said elements being combined substantially as described, whereby the pivot ot' the bar is placed between the lamp and the reflector, and the latter can be completely revolved around, to throw the light to any part of the room, as set forth.

2. In abracket-lamp,thelongitudinal bar 13, pivoted at or near its center on a pivot carried by a horizontally-swinging bracket, around which pivot the bar is capable of describing a complete circle, said bar having free ends, to one of which is directly attached a bracket, 0, carrying a removable lamp, while to the other end is directly attached a reflector, said elements being combined substantially as described, whereby the pivot of the bar is placed between the lamp and the reflector, and the lamp and reflector can be revolved in a complete circle, to throw the light to any part of a room, as set forth.

3. The adapter I), provided with a pin or stud, c, and constructed, as described, to be detachably connected with the support a of a bracket, in combination with the longitudinal bar B, pivoted at or near its center on the said pin or stud, and having free ends, to one of which is directly attached a reflector, said bar being capable of freely revolving, as set forth, whereby the lamp and reflector can be made to describe a complete circle, as described.
